With the promotion of the concept of sustainable development, the application of new energy has attracted more and more attention from all countries. At this stage, the global energy structure is still dominated by fossil fuels, and it is bound to face the pressure of transformation.
In this context, the Nordic country of Sweden has taken the lead in creative exploration of the application of new energy vehicles, the most notable of which is the project to spend 14 million euros to lay electric rails on the road.
Project DescriptionThe approximately 25-metre-long power railroad is installed underneath a busy road in Stockholm and is no different from a normal road. Its core function lies in its ability to capture the kinetic energy generated by the car while it is in motion.
This part of the kinetic energy is converted into electrical energy output through mechanical sensors, so as to realize the supplement to the urban power supply system. This technology works similarly to high-speed rail and trams, but burying the rails deep underground, which not only greatly reduces the complexity of construction and maintenance, but also ensures the safety of pedestrians.
The power rail can also provide real-time charging for all types of new energy vehicles, especially electric vehicles. An automatic sensor under the vehicle recognises the supply rails and dynamically connects and charges them via an adjustable charging arm.
The charging data is also fed back to the in-vehicle system for reference. Challenges in the implementation of the projectAlthough the technology has been successful in concept and practice, Sweden still faces many challenges in scaling it up nationwide.
The project cost nearly 2 million euros for just two kilometers of test tracks, and tens of billions of euros are expected to be needed to lay it to meet national demand, as well as a lot of capital investment for later maintenance and retrofitting of traditional cars.
A complete power infrastructure still needs to be built, and the existing power system is difficult to meet the charging needs of electric vehicles across the country. Although the pilot phase of this project has been successful, it is still far from being commercialized.
Although Sweden's power supply rail project has been stranded for various reasons, its pioneering significance in the field of new energy vehicles is still worthy of recognition. This innovative attempt provides a new idea for automobile transportation to achieve "energy self-sufficiency", and is also a useful exploration for cities to create a sustainable energy structure.
With the continuous advancement of technology, the related economic and infrastructure problems are expected to be properly addressed. Therefore, as a successful example of environmental protection and scientific and technological innovation, this project still has broad application prospects and deserves our continuous attention.
ConclusionThe road power rail plan jointly launched by Sweden** and the company is a bold innovation in the field of new energy transportation in the country. Although there are still problems, it points out the direction for the development of new energy vehicles and provides valuable experience for the construction of low-carbon transportation around the world.
We have reason to believe that with the improvement of the technical level, this project will be fully realized in the near future, and make outstanding contributions to the green and sustainable development of Sweden and the world.
